Lighter, further, with fewer environmental effects
Rolling resistance amounts to approx. 20 per cent of the vehicle’s fuel consumption. It affects energy efficiency and, therefore, also the operational costs and carbon dioxide emissions of the vehicle. The lower the rolling resistance is, the lower the fuel consumption.
The energy efficiency class indicates rolling resistance. It indicates the tyre's share of the vehicle's fuel consumption and CO2 emissions.
The categories start from A (green) and end with G (red). Class A is the best, class G is the weakest, and class D is not used.
Five full tanks during the tyre’s lifetime
Annually, fuel savings between the best and weakest tyre amount to approx. 90 litres. During the entire operating life of the tyre, the amount of fuel equals five full tanks (240 litres). *
What is the difference in fuel economy?
Additional fuel consumption 1/100km
Using highly efficient class B tyres, a passenger car uses approx. 0.1 litres less fuel per 100 km than a class C tyre. The difference in consumption between the best and weakest tyre (A-G) is significant, at around 0.6 l/100 km. The lightly rolling tyres also reduce CO2 emissions by 14 g/km.
›› Best and weakest. Classes A to G, savings of up to 5 full tanks during the operating life
›› Adjacent classes. For example: B to C, savings 0.1 l/100 km
* Car's fuel consumption 7 l/100 km. Estimated annual mileage 15,000 km, 40,000 km during the tyre's lifetime.
Fuel savings and road safety are highly dependent on the driver’s behaviour. Take into account the following issues:
- Economic driving can significantly reduce fuel consumption
- To optimise road safety and driving comfort, tyre pressure needs to be checked at regular intervals
- If the tyre pressure is too low, the tyre wears out much quicker than usual; it also affects fuel consumption and poses a clear risk in terms of road safety
- A responsible motorist is always aware of the properties and condition of his/her tyres. Only a driver who knows the vehicle and tyres can adjust the speed and safety distance to match the current weather.
